Boom
c. Secondary Intermediate Boom Retract Chain
Removal and Replacement
1. Park the vehicle on a hard, level surface.
2. Fully retract the boom and raise the boom to a
horizontal position. Place the travel select lever in
(N) NEUTRAL, move the neutral lock lever to (N)
NEUTRAL LOCK position, engage the parking brake
switch and shut the engine OFF.
3. Remove the thumbscrew (15), lockwasher (16) and
flat washer (17) holding the rear cover (18) to the
rear of the outer boom (19). Lift the rear cover
straight up until the capscrew in the top of the cover
clears the retaining hole in the top of the outer boom.
Remove the cover from the outer boom.
4. At the front underside of the boom, locate the
intermediate boom retract chain elastic locknut (20).
Record the amount of threads extending beyond the
elastic locknut. This measurement will be the
starting point for adjustment of the retract chain after
installation.
5. At the front underside of the outer boom, remove the
elastic locknut (20) and flat washer (21) holding the
retract chain threaded clevis (22) to the mounting
tab. Save the flat washer and discard the elastic
locknut.
6. The chain clevis may have a threaded hole on the
end of the clevis (25). A string or wire can be
attached to the retract chain clevis using a threaded
eye (23) or a flat washer tack welded to a capscrew
(24) or through the clevis fingers. The outside
diameter of the eye or flat washer must be smaller
than the diameter of the threads on the clevis. The
string or wire will be used to pull the chain back
through the boom during the reassembly.
7. Attach a string or wire to the threaded eye (23 or 24),
that was installed in Step 6. The string or wire must
be long enough to pull the clevis and chain through
the outer boom.
